Paste any domain — a suspicious link from an email, or your own brand's domain to see how easily it could be faked. Instant impersonation-risk score, computed entirely in your browser. Nothing you type ever leaves this page.
Tip: paste the full URL if you like — we will extract the domain.
Lookalike characters — "paypa1.com" swaps a letter for a number; "rnicrosoft.com" uses r+n to mimic m. Punycode — domains starting with xn-- can render as foreign characters that look identical to Latin letters. Hyphen stuffing — "secure-login-paypal-support.com" buries the real brand in noise. Abused TLDs — some cheap top-level domains show up in phishing far more often than others.
DomainGuard watches your actual domains around the clock and alerts you the moment a lookalike is registered. This free check is the first taste.
